Free video game library manager for Mac & Windows
Backlog Zero started as a question: how many times do I own the same game? It grew into a free video game library manager for Steam, Xbox, GOG, Epic Games, and Amazon Luna — with duplicate detection, session tracking, backlog goals, and no judgment about the size of the pile.
Available for macOS 12+ and Windows 10+.
What's inside
Multiple platforms. A wishlist that never gets checked. A backlog that only grows. Backlog Zero was built to handle all of it — no account needed, no data leaving your machine.
Every game you own, on every platform, in one place. Add games, assign statuses, fetch cover art, spot duplicates, and actually know what your collection looks like.
Find the cleanup work worth doing: duplicates, missing tags, genre gaps, unresolved covers, no-cover exceptions, stale syncs, and optional reference gaps.
Log what you play and set a target for your backlog. Sessions feed your stats. Goals keep you honest. Together they turn good intentions into something measurable.
Watch prices, spot historical lows, catch stale deal data, and see which wishlist games already live in your library before you buy them again.
Can't decide what to play next? Backlog Zero picks from your unplayed games so you don't spend forty minutes scrolling and end up watching TV instead.
Your library data lives in a file on your computer. No server. No account. No one else involved. It's yours in the most literal sense.
This is probably you
Backlog Zero is not where you play. It's where you figure out what you own, what you keep rebuying, and why choosing something to play has become a small administrative project.
Steam, GOG, Xbox, a bundle from 2017. Backlog Zero shows the overlap before it becomes purchase number four.
Launchers are useful, but your backlog does not respect launcher boundaries. Neither should your records.
The Backlog Picker gives your unplayed pile a fighting chance when your brain has too many options open.
Sessions, goals, habits, and completion patterns without turning your hobby into a spreadsheet maintenance job.
Your collection data lives on your machine. No cloud profile required just to admit you still haven't finished that one RPG.
Platform support
The overlap might surprise you.
Not another launcher
Playnite, GOG Galaxy, Steam, Epic, and the rest all have a job: get you into a game. Backlog Zero has a different job. It keeps a personal record of what you own, where you own it, what you've played, what you've ignored, and what you somehow bought twice.
It is the quiet ledger for the whole mess — not the front door to every executable on your computer.
New in v1.2.0
Why Backlog Zero
Most game collection trackers require an account, sync your library to someone else's server, or lock features behind a subscription. Backlog Zero is a free game library manager for Mac and Windows that works entirely offline — your game collection, play history, and backlog data never leave your machine.
It unifies your Steam, Xbox, GOG, Epic Games, and Amazon Luna libraries into a single view, automatically detects duplicate games you own across multiple platforms, and tracks your unplayed backlog so you always know what you own and what's still waiting. Library Health turns cleanup into focused review flows for tags, genres, cover art, play status, no-cover resolutions, and optional reference gaps.
Whether you're trying to organize a game collection that spans five launchers, stop buying games you already own, or finally make a dent in a backlog of hundreds of unplayed titles — Backlog Zero was built for exactly that. See everything it does or download it free.
